SPE(iIEICA'J'ION fOrmng part Of, Letters Patent NO. 402,356, dated April 30, 1889.

v boiler or receptacle at the highest point of the circulating system.

In my lmprovement I employ, in connection with the usual surrounding walls and tire and ash chambers, corrugated water bases, L- shaped in sectional plan, which bases surround the iire L chambers on three sides and are adapted to contain water. I also employ vertical corrugated water-chambers, that are set upright and edgewise upon the main portion of the bases, and from each side of these ver- `tical corrugated water-chambers there are corru gated circulating water-pipes, and Iemploy stand pipes connected at their upper and lower ends with the aforesaid bases and upright chambers, and supported by the standpipes. There is a water or steam receptacle. The partsare so arranged that the products of combustion and heated gases from the fire pass up between one series of corrugated circulating-pipes and against one side of the upright chambers and over the top of said chambers, and down between the second series ot' corrugated circulating-pipes upon the other side of the upright chambers, and said products of combustion further pass beneath avertical deiiecting-plate and up and around and between the stand-pipes, and so away to the chimney, thus thoroughly heating the various parts of theapparatus and their circulating-pipes.

In the drawings, Figure 1 is a vertical section and partial elevation of my improved steam-boiler. Fig. 2 is a sectional plan at the line of Fig. l, and Fig. 3 is a partial cross# section and front elevation of the same.

The side walls, A, end walls, B, and front wall, C, and the top D are preferably of brick, as is usual in such steam-boilers3 and E represents the grate-bars, F the ash-pit, F the ashdoor,-E the coaldoor, G the upper doors, H the water-gage, I the safetyvalve, and K the steam-pipe. These parts are oi usual and well-known construction in all steam-boilers of this type, and do not require any further description, as they may be made in any wellknown or usual manner.

d d represent the corrugated water-bases, which are vat vthe sides and back of the rechamber above the grate-bars E, and said water-bases are L-shaped, as shown in the pian, Fig. 2, and the same take the place of iirebrick, so that no fire-brick is employed around three sides of the iire. These two water-bases of the short arms of the water-bases d a', the

corrugations of said upright chambers b b h2 being along their vertical opposing edges, as will be seen in Fig. 3, where they set together, and said upright chambers extend across and fill the space between the side walls of the boiler. Each one of said upright chambers b b h2 has connected to its vertical sides a series of U-shaped corrugated water-pipes, c c', these pipes each having, as shown in Fig. l, two horizontal arms and one vertical arm, and forming a water-conduit from the lower to the upper portion of said upright chambers, and these corrugated pipes c c are securely fastened to the upright chambers in any usual or well-known manner to form a water-tight joint.

d d( d2 represent stand-pipes, and 'said stand-pipes are supported upon the ledge B of the back wall, and the upper ends of said stand-pipes extend outside of the top wall, D, and there are pipes e andv a branch, e', connecting the lower ends of each of the stand pipes with the back of the water-bases a a', and there are pipes e2 connecting the upper ends of the stand-pipes with the upper ends IOO of the upright chambers b h b2, and there are branch pipes i connecting the back of the water-bases a a with the lower portion of each of the vertical chambers l) h b2.

f representsa boiler or receptacle in which the steam is collected, and the same is connected to the stand-pipes (Z d d2 by the short branch pipes j. The waterbases a a', the upright chambers b b h2, the series of corrugated pipes c e', the stand-pipes d d d'2, the pipes and branches c e "3, the branch pipes f', and the lower portion ot` the receptacle f are all supposed to be filled with water, which water circulates by the branches 'i 'from the corrugated bases a a into the upright chainbers b b b2, from the lower portion of said upright chambers through the lower horizontal arms of the corrugated pipes c c', up the vertical arms of said pipes, and through their upper horizontal arms into the upper part of said upright chambers, through the pipes e2 to the upper part of the stand-pipes d d2, down to the stand-pipes, and back into the corrugated water-bases a a by the pipes and branches e c', the steam as formed illing the receptacle f, or iillin g both the upper part of the stand-pipes and receptacle, and said steam can pass away for use by the steampipe K, and should the pressure become too great said steam can escape by the valve l.

A plate of metal, g, extends across between the side walls, A, and down from the top D directly in front of the stand-pipes d d d2, and this plate acts to divert the products of combustion. The path of said products of combustion and heated gases is shown by the arrows, Fig. l, the same passing up between the innersurface of the water-bases a a', up through the series of corrugated pipes c, over the top of the upright chambers b b b2, and down between the pipes c2 and the series. of corrugated pipes c', around the lower edge of the plate g, and up between the stand-pipes d d d2 and away by the tlue Z to a chimney, thus heating all the parts of the apparatus eiectually.

My improved apparatus is adapted for the quick and economical making of steam, and the different parts of its construction are preferably made of cast or malleable east metal, and the parts of said apparatus are made interchangeable, so that any one or more parts when worn or burned out can be readily or quickly replaced.

I claim as my invention*- l. ln a steam-boiler, the combination of corrugated waterbases surrounding the lirechamber on three sides, and upright corrugated chambers set edgewise and resting upon the water-bases and extending across between the side walls of the boiler, and pipes connecting the water-bases with the upright chambers, substantially as set forth.

2. In a steam-boiler, the combination, with the fire-eh amber and grate-bars, of corrugated water-bases surrounding the fire-chamber on three sides, the upright water-chambers set edgewise and corrugated on their contiguous faces and resting on the water-bases, and pipes connecting the water-bases and upright chambers together, and series of U-shaped corrugated pipes connected upon each side of the upright water-chambers, substantially as set forth.

3. The combination, in a steanrboiler, with the L-shaped corrugated water-bases ay a', and the upright water-chambers resting thereon, and pipes connecting the bases and chambers, of the stand-pipes d d (Z2, and a steam-receptacle connected therewith, and pipes connectn ing the lower portion of the stand-pipes to the water-bases and the upper portion of the stand-pipes to the top of the Vertical waterchambers, substantially as and for the purposes set forth.

4. In a steam-boiler, the combination, with the L-shaped water-bases, the upright Waterellambers, and the series of U-shaped corrugated cireulating-pipes c c', connected. to the opposite sides of the upright water-chambers, of a delieeting-plate, g, back of the circulating-pipes c', whereby the products of combustion passing up between the pipes aand over the upright chambers are caused to pass down between the pipes c before reaching a chimney, substantially as set forth.

Signed by me this 27th day of September, 1888.
